I have a 1983 380sel that has no reverse lights. I have swapped the bulbs for new ones, to no avail. I would swap the fuse, but it also runs other things that work just fine, so I would venture a guess that it is not a fuse.

Any ideas?

Could be the switch that activates the back up light circuit when you put the transmission in reverse.

Where is that switch located and how might I fix it? Any idea about the part number?
